nanocatalyst) was prepared by the co-precipitation method and characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray powder diffraction and Brunauer-Emmett-Teller surface area analysis. CuO/ ZnO/Al 2 O 3 nanocatalyst proved to be a very efficient catalyst on the synthesis of propargylamines under solvent-free conditions in high yields. Moreover, the catalyst can be recyclable without reducing catalytic activity up to five times.
